Abstract

A vehicular slider window assembly includes a frame having upper and lower rails. A fixed window has an opening and the rails are attached at the fixed window. A movable window is movable between a closed position and an opened position. A carrier disposed at a lower edge of the movable window moves with the movable window between the opened and closed positions. A sensing system determines when the movable window is in the closed position and includes a switch assembly that is actuated when the movable window is in the closed position. The switch assembly includes a switch device within a housing. A portion of the housing is an end stop configured to limit movement of the carrier when the movable window is in the closed position. The switch device includes a contact and, when the movable window is in the closed position, the contact actuates the switch device.

First claim

The invention claimed is:

1. A vehicular slider window assembly, the vehicular slider window assembly comprising:
a frame portion having an upper rail and a lower rail;
a fixed window panel, the fixed window panel having an opening, wherein the upper and lower rails are fixedly attached to an interior surface of the fixed window panel;
a movable window panel that is movable along and between the upper rail and the lower rail, wherein the movable window panel is movable between a closed position, where the movable window panel closes the opening, and an opened position, where the movable window panel is located at least partially along the fixed window panel away from the opening;
a carrier disposed at a lower perimeter edge region of the movable window panel, wherein the carrier is received in a channel portion of the lower rail and moves along the channel portion of the lower rail with the movable window panel as the movable window panel is moved between the opened position and the closed position;
a sensing system operable to determine when the movable window panel is in the closed position and when the movable window panel is not in the closed position, wherein the sensing system comprises a switch assembly that is actuated when the movable window panel is in the closed position;
wherein the switch assembly comprises a switch device disposed within a housing, and wherein at least a first portion of the housing is part of an end stop;
wherein the end stop is disposed at an end of the channel portion of the lower rail, and wherein the end stop is configured to limit movement of the carrier along the channel portion when the movable window panel is moved to the closed position;
wherein the switch device comprises a contact element that extends along the channel portion of the lower rail, and wherein, when the movable window panel is moved to the closed position, the contact element moves to actuate the switch device;
wherein, when the movable window panel is not in the closed position, the contact element does not actuate the switch device; and
wherein, responsive to the switch device not being actuated and the sensing system determining that the movable window panel is not in the closed position, the sensing system generates a first output signal to alert a driver of a vehicle equipped with the vehicular slider window assembly that the movable window panel is not in the closed position.

2. The vehicular slider window assembly of claim 1 , wherein the sensing system generates a second output signal different than the first output signal responsive to determining that the movable window panel is in the closed position.

3. The vehicular slider window assembly of claim 1 , wherein the movable window panel is movable between the opened and closed positions by a cable drive system, and wherein cables of the cable drive system are guided by cable guides at opposite ends of the channel portion of the lower rail, and wherein the end stop of the switch assembly comprises one of the cable guides.

4. The vehicular slider window assembly of claim 1 , wherein the end stop is configured to contact the carrier when the movable window panel is moved to the closed position, and wherein, when the movable window panel is moved to the closed position and the first portion contacts the carrier, the contact element is moved by the carrier to actuate the switch device.

5. The vehicular slider window assembly of claim 1 , wherein the fixed window panel comprises first and second fixed window panels having the opening therebetween.

6. The vehicular slider window assembly of claim 1 , wherein the fixed window panel comprises a single fixed window panel having the opening therethrough.

7. The vehicular slider window assembly of claim 1 , wherein the switch device and associated circuitry are part of a unit, and wherein the unit is disposed in the first portion of the housing that is integrally formed with the end stop at the end of the channel portion of the lower rail.

8. The vehicular slider window assembly of claim 1 , wherein the switch assembly comprises an elastomeric cover that is disposed at least partially over the housing and over the contact element, and wherein, when the movable window panel is moved to the closed position, the cover flexes to allow for movement of the contact element to actuate the switch device.

9. The vehicular slider window assembly of claim 1 , wherein the first portion is integrally formed with the end stop, and wherein the housing comprises a second portion that is snap-attached to the first portion to encase the switch device in the housing.

10. The vehicular slider window assembly of claim 9 , wherein the second portion comprises locating elements that locate the switch device at the second portion prior to snap-attaching the second portion to the first portion.

11. The vehicular slider window assembly of claim 1 , wherein the first output signal causes activation of an indicator in a cabin of the vehicle to alert the driver of the vehicle that the movable window panel is not in the closed position, and wherein the indicator in the cabin of the vehicle is viewable by the driver of the vehicle.

12. A vehicular slider window assembly, the vehicular slider window assembly comprising:
a frame portion having an upper rail and a lower rail;
a fixed window panel, the fixed window panel having an opening, wherein the upper and lower rails are fixedly attached to an interior surface of the fixed window panel;
a movable window panel that is movable along and between the upper rail and the lower rail, wherein the movable window panel is movable between a closed position, where the movable window panel closes the opening, and an opened position, where the movable window panel is located at least partially along the fixed window panel away from the opening;
a carrier disposed at a lower perimeter edge region of the movable window panel, wherein the carrier is received in a channel portion of the lower rail and moves along the channel portion of the lower rail with the movable window panel as the movable window panel is moved between the opened position and the closed position;
a sensing system operable to determine when the movable window panel is in the closed position and when the movable window panel is not in the closed position, wherein the sensing system comprises a switch assembly that is actuated when the movable window panel is in the closed position;
wherein the switch assembly comprises a switch device disposed within a housing, and wherein at least a first portion of the housing is part of an end stop;
wherein the end stop is disposed at an end of the channel portion of the lower rail, and wherein the end stop is configured to limit movement of the carrier along the channel portion when the movable window panel is moved to the closed position;
wherein the movable window panel is movable between the opened and closed positions by a cable drive system, and wherein cables of the cable drive system are guided by cable guides at opposite ends of the channel portion of the lower rail, and wherein the end stop of the switch assembly comprises one of the cable guides;
wherein the switch device comprises a contact element that extends along the channel portion of the lower rail, and wherein, when the movable window panel is moved to the closed position, the contact element moves to actuate the switch device;
wherein, when the movable window panel is not in the closed position, the contact element does not actuate the switch device;
wherein the end stop is configured to contact the carrier when the movable window panel is moved to the closed position, and wherein, whe
